Bioengineers clear major hurdle on path to 3D printing replacement organs. Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs with a breakthrough technique for bioprinting tissues. The new innovation allows scientists to create exquisitely entangled vascular networks that mimic the body’s natural passageways for blood, air, lymph and other vital fluids.

The research is featured on the cover of this week’s issue of Science...

Synthetic proteins engineered to recognize overly active biological pathways can kill cancer cells while sparing their healthy peers, according to a study by researchers at the Stanford University School of Medicine...

When combined with a diet low in saturated fats, eating walnuts may help lower blood pressure in people at risk for cardiovascular disease, according to a new Penn State study.

In a randomized, controlled trial, researchers examined the effects of replacing some of the saturated fats in participants’ diets with walnuts. They found that when participants ate whole walnuts daily in combination with lower overall amounts of saturated fat, they had lower central blood pressure.

According to the researchers, central pressure is the pressure that is exer...

Popular protein great for increasing muscle mass, but could reduce your life-span – researchers say to vary protein intake. Researchers have examined whether there are any ongoing ramifications or potential side-effects from long-term high protein intake or from consuming certain types of amino acids.

Led by academics from the University of Sydney’s Charles Perkins Centre, Professor Stephen Simpson and Dr Samantha Solon-Biet, suggests that while delivering muscle-building benefits, excessive consumption of branched-chain amino acids (BCAAs) may reduce lifespan, negatively impact mood and...
